y invention is an improvement in alcohol extractors for brew kettles,and has for its object to provide mechanism of the character specified,especially adapted for condensing and extractingthe alcohol from beer toprovide a beer free from alcohol.

In the drawings:

Figure 1 is a horizontal section through the improvedextractor on line1-1 of Fig. 2.

Fig. 2 is a' vertical section through the center lineof the device.

In the present embodiment of the inven tion a casing 1 is provided,having marginal flanges 2 at its top and bottom, and the casing isjacketed, as indicated at 3. throughout the greater portion of itslength. Within the casing and coaxial therewith is arranged 'a doublewall casing 4, the said casing extending from near the bottom to nearthe top of the casing 1. The jacket 3 has a water inlet 5 at its bottomand a water outlet 6 at its top, and water is supplied to the bottomof-the casing 4- by means of an inlet pipe 7, the water discharging fromthe casing through an out-let pipe 8 at the top.

The vapor from the brew kettle passes upwardly through the casings,between the outer casing and the outer Wall of the inner casing,. andthrough'the inner casing, and the alcohol is condensed during itspassage. A series of troughs 9' is supported by the double wall or innercasing, the said troughs or gutters being annular in formv andencircling the casing, and being arranged at spaced intervals.

A `series of gutters or troughs 10 is supported bythe outer casing 1,-and these troughs'lO, which are also annular in form and arranged inspaced relation, alternate withthe troughs 9. Overflow or drain pipes 11lead from the troughs 9 and deliver to the troughs 10, so that thecondensed alcohol may ow'from-the troughs 9 to the Vtroughs 10,eventually reaching the lowermost trough 9, from whence the saidcondensed products pass by means of a pipe 11 to the main alcoholcatcher 12, which is a trough supported by the casing 1 near the bottomthereof, and an outlet 13 is pro-` vided or the alcohol at this point. Aperforated balie plate 14 is arranged near the top of-the inner casing,just below the uppermost trough 9, `forAv slowing the flow of the vaporthrough the inner casing.

In operation, the vapor yfrom the brew kettle passes upwardly throughthe inner and the outer casings, and the alcohol is condensed by thecold water in the casing. This condensed alcohol is collected by thetroughs 9 and l0 and iows'from one trough i to the other by way of thefpipes 11, eventually reaching the Collector 12, from whence it flows toa suitable receptacle.

In order to collect the alcohol vfrom, the I inner casing or column aunnelshaped receiver 15 is arranged beneath the llowerendV of the innercasing, and this receiver delivers by a pipe 16 tothe trough 12 at theopposite side from theoutlet 13.' The vapor that is condensed withinthe" casing 4 is collected by the collectorlj anddelivered to thecollector 12.5 v

It will be noticed that the-vapors are oonstrained to follow a sinuouscourse from the, bottom to the top of the extractor andtheyf are thusslowed in their passage, the troughsacting as baille platesor thispurpose. v
